this may just be the latest way firefox works.  it reports linux x86_64
everywhere except a handful of places like windows or macos or mobile.


one thing i've noticed the radeon driver still has issues with some
sort of cache issue, where the display is incorrect some relatively
large portion of the time, menus wrong, that clear up when you move
the cursor near them, weird pixelated stuff.  it only happens really
poorly on one specific system for me -- a "AMD E2-7110 APU with AMD
Radeon R2 Graphics" laptop, that seems to be the last generation of
APUs that used "radeon" instead of "amdgpu" (i have another laptop
with a very slighty older CPU -- same micro-arch, bulldozer#4 -- but
comes with amdgpu that works fine.

anyway, i wonder if the ring timeouts are because values aren't 
making it into the right place in time (bad cache flush type thing?)
